[Q] how to run a phone without battery only by connecting charger

It should work by taking the protection circuitry from an old battery and take a power bank that uses a lithium cell and connect the + & - of the power bank to the + & - of the battery circuitry. This way it should trick the phone into thinking it has a fully charged battery installed, plus giving the extra overcurrent protection from both boards. Upvote 0 Downvote. J.

Using a dc power supply instead of batteries

Unfortunately, just a 6 V supply won''t do it. You really need a ±3 V supply. Or, you can get two 3 V supplies and connect the + of one to the - of the other. That common connection will be the ground of your circuit. The remaining + and - ends are the +3 V and -3 V ends. The latter is probably easier to source. Basically, get two cheap 3 V

Charging a 45w laptop with a 65w charger. bad? (Explained)

You can use a 65w charger instead of a 45w charger. If the voltage is the same, the laptop will only utilize the power it requires from the charger. You will be fine. However, it is beneficial to use a higher watt charger than a lower one because using a lower watt can put a load on the charger and can cause heating. In this blog post, we will further explain what
